The following tables give a brief explanation of the individual parameters and their uses:

Parameter 1 — Autobaud Enable

When enabled, the stack light automatically communicates at the network baud rate detected

at power-on. When disabled, the baud rate must be set correctly by the user during node

commissioning. This parameter’s setting takes effect after a module reset or at power-on.

Note: Only valid when rotary switch is set between 3…9. The default value is Enabled.

Parameter 2 — Off-to-On Delay

The Off-to-On delay determines the amount of time for which an input signal must be fully

present before the stack light updates the I/O. It is a means of filtering for noise on input

lines. The value must be set in units of microseconds. The default is set to 0 s to ensure

proper filtering on noisy lines, but it can be reduced depending on the application. (Not Used)

Parameter 3 — On-to-Off Delay

The On-to-Off delay determines the amount of time for which an input signal must be fully

absent before the stack light updates the I/O. It is a means of filtering for noise on input lines.

The value must be set in units of microseconds. The default is set to 0 s to ensure proper

filtering on noisy lines, but it can be reduced depending on the application. (Not Used)
